Didn't receive head start reward

[allday9128_MLBTS]

Coming into this season I had everything done for the rewards except TA set 3, I got the first 4 rewards at the start of the season(35k xp, 7,500 stubs, and 5 Biah packs)

Finished TA3 yesterday and didn't receive the guaranteed diamond duo player. Figured to give it some time and see if it shows up and still nothing. TA set 3 and the pack are both checked off in the recap and reward screen. Even double checked my open pack history to see if I opened it and didn't remember.

Are these only available right at the start of the season? Or is this something I need to open a ticket for?

You have to have them done before the new season starts. If you do them after, it will apply the checkmark, but it doesn't actually give you the reward.
